Mendel noted that the Honda Accord Plug-In Hybrid model would be eliminated as well. Available only in a handful of states, it has sold just 1,000 units in two years.

Not all the news from Honda involved ending the sale of green models, however. The company noted that the Accord mid-size sedan will be updated for 2016--and so will its hybrid version.

While there may be a temporary interruption in Accord Hybrid supplies as production of that model is moved from Ohio to Japan, the company expects more Accord Hybrids to be available than previously once production resumes.

And, Mendel said, the 2016 Accord Hybrid will feature an updated version of the company's two-motor hybrid system that will deliver even higher fuel-economy ratings than the current sedan's 47 mpg combined.

He also said the updated two-motor hybrid system will be used in an additional model in future, though he declined to characterize that model in any way.

Finally, Mendel reiterated the company's plans to introduce three new dedicated green vehicles.

The company will launch a production version of its Honda FCV Concept powered by a hydrogen fuel cell, effectively a successor to the Honda FCX Clarity, of which about 60 were delivered in the U.S. over seven years.

And it will launch both a dedicated battery-electric car and a dedicated plug-in hybrid model "by 2018," though again Mendel declined to provide any further details about the vehicles--including body style(s), size, range, or site of manufacture.

Over the last two years, Honda has eliminated six separate green models. Here's hoping that the future entries are higher-volume.
